I really cannot understand what you are doing, since a variety of your
statements variously do not make sense or seem impossible.
- there is no usecase to be a context
- why are you using Complete OCL in the OCL Console
To see if there is any problem, I created a UML model comprising
I then selected actor a, and evaluated
in the OCL Console against the Ecore or UML M2 meta-model and got 'false'.
I then set a's useCase to be u and evaluated again and got 'true',
which is exactly what I would expect with the expression I suggested.
If you cannot make this work, you must describe what you are doing very
carefully and accurately so that whatever strange things yoiu are doing
can be identified.
